Hi all, I have a maranzt SR4300 for my amp and a pair of Celestion Ditton 44's for my lef and rights, I don't have center, or any rears. I am preferably looking for some tall rears although small ones would be fine. My center I think i'm going to hold back on for a bit because there not that important are they? My budget is around £100. this amp has 6.1 so I would have my two fronts yes, then my two backs, then my center and would I then have another speaker inbetween my two rears? Any advice would be greatly appreciated.
